403 Ancient Water Management in The
ARAM, 13-14 (2001-2002), 403-421 U. AVNER 403 ANCIENT WATER MANAGEMENT IN THE SOUTHERN NEGEV UZI AVNER INTRODUCTION The southern Negev is an extremely arid area, with summer temperatures above 400C, an average annual precipitation of 28 mm, and an annual potential evaporation rate of 4000 mm. This negative water balance causes the area to be poor in water sources and limits the Saharo-Arabian vegetation almost to- tally to wadi beds. Certainly, the desert presents several obstacles to the devel- opment of human communities, the foremost of which is the scarcity of water, for drinking, for everyday uses, for animals and for agriculture. Considering the environmental conditions, one would expect the Southern Negev to be al- most devoid of ancient remains of human presence and activity. However, the harshest part of this area, from ‘Uvda Valley and southward (see Map 1), is surprisingly rich in archaeological sites. A complete sequence of settlement is found during the last 10,000 years, with a wide range of activi- ties such as hunting, grazing, agriculture, trade, copper production, some gold production and others (Avner et al 1994). In this article I will describe several methods of water exploitation in the region. The first will concern the early agricultural settlement in ‘Uvda Valley, 6th to 3rd millennia B.C., the others relate to the Nabatean and the Early Islamic period. AGRICULTURAL SETTLEMENT IN ‘UVDA VALLEY ‘Uvda Valley (Wadi ‘Uqfi in Arabic), 40 km north of the Gulf of Aqaba (Fig. 1), was first briefly described by A. Musil (1907:180-182, 1926:85).
